Definitions

  • the invention relates to a process for selectively separating iron from other metal ions, in particular ions present in certain oxidation catalysts.
  • It also relates to a process for recycling catalysts in the reaction for the oxidation of alcohols and optionally ketones to carboxylic acids and more particularly the oxidation of cyclic alcohols and cyclic ketones to dicarboxylic acids, such as the oxidation of cyclohexanol and/or cyclohexanone to adipic acid.
  • adipic acid by nitric oxidation of a mixture of cyclohexanol and cyclohexanone. This oxidation is generally carried out in the presence of a catalyst comprising vanadium and copper.
  • the solution recovered after separation of the dicarboxylic acids and in particular of adipic acid is treated in order to allow the catalyst to be recycled in the oxidation reaction.
  • the metals present in the solution can be extracted by treatment with ion-exchange resins.
  • the solution, purified of metals comprises the byproducts from the synthesis of adipic acid, namely glutaric and succinic acids. Such a process is disclosed, for example, in U.S. Pat. No. 3,965,164.
  • the catalyst is enriched in iron at each recycling cycle. This enriching can decrease the efficiency of the catalyst or can also contaminate the adipic acid manufactured.
  • European Patent Application No. 0,761,636 provides a process which consists in treating the eluate comprising the iron, copper and vanadium ions with a second ion-exchange resin comprising aminophosphoric groups.
  • One of the aims of the present invention is to provide a novel process which makes it possible to selectively separate the iron from other metal ions, in particular from the vanadium ions, and thus to provide a very efficient process for the recycling of the catalyst for the oxidation of organic compounds, more particularly of alcohols and/or of ketones to carboxylic acids and more preferably still of cyclohexanol and/or cyclohexanone to adipic acid.
  • the invention provides a process for selectively separating the iron present in a solution in the presence of other metal ions, including vanadium.
  • These solutions are generally solutions originating from processes for the oxidation of an organic compound in the presence of a vanadium-based catalyst.
  • the solution comprising the said metal ions is treated with an ion-exchange resin comprising diphosphonic acid groups.
  • the iron is fixed by the resin; the metal ions, such as, in ticular, copper and vanadium, remain in the treated solution.
  • FIG. 1 is a graph showing the percentage of metal fixed to resin as a function of the duration of treatment
  • FIG. 2 is a graph showing the percent metal ions fixed as a function of the duration of treatment
  • FIG. 3 is a graph depicting the percentage of metal ions fixed to resin as a function of the duration of treatment
  • FIG. 4 is a graph which shows the percentage of metal fixed to Diphonix® resin as a function of the duration of treatment
  • FIG. 5 is a graph showing the percentage of metal fixed to S-940 resin.
  • FIG. 6 is a graph showing the percentage of metal fixed to C467 resin.
  • the process of the invention makes it possible to fix to the resin at least 80% of the iron present in the solution.
  • the solution to be treated comprising the metal ions has a very low pH, advantageously of less than 3 and of preferably less than 2.
  • the ion-exchange resin also comprises sulphonic groups.
  • resins comprising diphosphonic acid groups and optionally suiphonic groups makes it possible, in a noteworthy way, to fix the iron present in a solution without fixing other metal cations, such as copper and more particularly vanadium.
  • This process applies more particularly to the recycling of the catalysts in reactions for the oxidation of organic compounds and more particularly of alcohols and/or ketones to carboxylic acids.
  • Such an oxidation process also constitutes a subject-matter of the present invention.
  • oxidizing agent a compound chosen from the group consisting of oxygen, air, peroxides, aqueous hydrogen peroxide solution and nitric acid.
  • the process of the invention makes it possible to carry out this removal of the iron by treatment of the solution comprising the various metal ions recovered after separation of the organic compounds and in particular of the carboxylic acid or acids formed.
  • This removal of the iron is obtained by treatment of the said solution with an ion-exchange resin comprising diphosphonic acid groups and optionally sulphonic groups.
  • the solution comprises the metal ions with the exception of iron ions, the latter being fixed to the resin.
  • the amount fixed is advantageously greater than 80% of the amount initially present in the solution.
  • the process of the invention makes it possible to recycle a solution comprising the metal ions of use in the catalysis with a minimum loss of the said ions and an absence of the iron ions or a presence of the latter at a very low and untroublesome concentration.
  • the treatment of the aqueous solution comprising the metal ions originating from the oxidation catalyst, namely, preferentially, vanadium and copper, with an ion-exchange resin comprising diphosphonic groups and optionally sulphonic groups makes it possible to remove the iron originating in particular from the corrosion of the plants and to recycle a catalytic solution with a minimum loss of catalytic elements, in particular of vanadium and of copper.
  • the process of the invention makes possible production of adipic acid with a very low, indeed even zero, content of iron.
  • the treatment of the solution is carried out, in a first embodiment, after extraction of the adipic acid and optionally separation of the precipitated vanadium.
  • the solution, purified of iron, can subsequently be treated with a second ion-exchange resin which fixes all the metal ions, in order to avoid recycling a solution comprising organic byproducts from the oxidation reaction, such as glutaric acid and/or succinic acid.
  • the recycled catalytic solution is composed of the solution from the elution of the said resin, which solution is generally composed of a nitric acid solution.
  • the treatment on an ion-exchange resin comprising diphosphonic acid groups and optionally comprising sulphonic groups can be carried out on the solution from the elution of the resin which makes it possible to separate the organic byproducts from the metal ions which are described above.
  • the ion-exchange resin comprising diphosphonic groups and optionally comprising sulphonic groups is regenerated by elution with an inorganic acid solution.
  • suitable inorganic acids of nitric acid, phosphoric acid or sulphuric acid.
  • an acid identical to that used to prepare the catalytic oxidation solution generally nitric acid, in order thus to avoid contamination of the reaction mixture by another acid.
  • the conditions for carrying out the treatment on an ion-exchange resin in accordance with the invention are the conventional conditions for the use of resins.
  • the temperature for carrying out this treatment can vary from room temperature (approximately 20° C.) to a temperature of approximately 100° C., preferably between 30° C. and 80° C.
  • the concentration of the acidic regeneration solution is conventional. It can, for example, be between 10% and 40% by weight.
  • ion-exchange resins in accordance with the invention comprising diphosphonic acid groups and optionally sulphonic groups are, for example, those disclosed in U.S. Pat. Nos. 5,449,462 and 5,281,631.
  • the resins are obtained by polymerization of various monomers, some of which comprise diphosphonic acid groups.
  • the resin can be a polystyrene resin with diphosphonic groups.
  • the resin can also comprise carboxylic groups and/or sulphonic groups.
  • 600 ml of an aqueous solution comprising 1.3% of nitric acid, 10,485 ppm of copper ion, 1353 ppm of iron ion and 281 ppm of vanadium ion are introduced into a receptacle.
  • the mixture is stirred for variable times.
  • the concentration of metals in the solution is measured after being brought into contact for variable periods of time.
  • the percentage of metal fixed to the resin as a function of the duration of treatment is represented in FIG. 1 .
  • the treatment thus makes possible selective separation of the iron from the other metal ions and in particular from the vanadium.
  • the two resins used are respectively a resin sold under the name Purolite S-940 and a resin sold by the company Röhm & Haas under the tradename C467.
  • the percentage of metal ions fixed as a function of the duration of treatment is represented in FIGS. 2 and 3 for the resin S940 and C467 respectively.
  • Example 1 is repeated on a solution comprising 19.9% of nitric acid, 8875 ppm of copper, 1192 ppm of iron and 165 ppm of vanadium.
  • This solution corresponds to the solution of eluates with nitric acid of a cation-exchange resin on which has been treated a solution originating from a process for the oxidation of cyclohexanol with nitric acid.
  • the resin in accordance with the invention makes it possible to fix a large amount of iron (at least 60% of the starting amount) while fixing a minimum of the other vanadium and copper cations.
  • the resins, laden with iron, obtained in Examples 1 and 4 are regenerated by elution with various acidic solutions by passing 100 ml of elution solution through 10 ml of resin.
  • Example 1 Resin, Example 4 Cu Fe V Cu Fe V HNO 3 95 29 97 52 14 56 H 2 SO 4 91 35 95 50 21 53 H 3 PO 4 87 50 90 45 37 50
